Bridge CS 5 is broken on my computer and it all started when i installed Lion (10.7.2).

It seems as though whenever the computer is put into sleep it messes up Bridge and whilst the program will actually launch the application eithe does nothing or moving the window cause it to display in what I can only describe as multiple split screens as if there is a real problem with the refresh/redraw of the screen image. Also, clicking on workspace items does nothing.

I have reset preferences, purged cache, disabled startup scripts etc and I think I have been through all the advice given but to no avail. The only solution is to turn off the computer and log in again but that doesn't solve it all the time. I have loads and loads of free space; have checked mac disc permissions etc and nothing!!

I have noticed (and I have read this elsewhere) that when I do a screen shot by drawing a marque over the area the windows kind of go back to normal (hence the reason why I can't upload a screen shot) but in any case the application does not work.

Here might be the culprit, while 256 MB is the required minimum 512 MB is recommended. Try to play with the various Graphics Processor settings in the PS preferences Performance tab and see if this speeds things up. (under advanced disable OpenCL)

And you can also choose to enable the 'Use software rendering' option in the Bridge Advanced preferences tab.

As said, minimum is minimum, every new edition takes more power of the Graphic card to enable all new futures. If possible upgrade your Graphic Card, 1 GB VRAM becomes quit common for newer cards and you will benefit from this for sure.

I have performed your steps above and it seems to have sorted out the issue. Also, I realised that I set the application to preview everything on the desktop when it opened and I feel that wasn't helping either.
